I don't believe Ron is the informer. My guess is that it was Charles or his mother or both. A car matching the description of Donna's was seen in the area of the house where Charles' mother lived. We heard it on the scanner. Misty had been living there. A day later Charles' mother was arrested!!!! And then the road rage between Charles and Ron/Misty shortly after that. Then, we heard on the scanner Charles being brought into the CID Office by a Detective. We heard Browns Fishcamp to CID and knew it was Charles. We assumed it was about the Road Rage. My feeling is that CJ is the informer. He was hanging over at Tyler quite a bit.
It is also my opinion that Misty got caught with the most drugs, and in areas where she might have been near a school etc., I don't think that fact that she has more charges is an indication that she was anything but the one running the drugs for someone else. She doesn't in My opinon have the capacity to orchestrate this, work with bigger dealers etc. If anything they may have been working for Hank Sr. Just my personal opinion.
